Tow-all 'whom t Amay concern.' l

Be it known that l, JOHN DE LACKNER, a .-citizenoffthe United States,residing at Long IslandCity, in the county of :Queens and State of `NewYork, have inventeda certain new andv usefulImprovement. in Corks for,Thermos Bottles, of which thc following vis a Yspeciication.

My invention .relates to vthat class of containers which are ,popularlyknown as 'thermos bottles.' These bottles,'which are designed tomaintain the temperature ofthe liquid contained therein are generally4provided with vvery long tightly fitting .coi-ks in Yorder to `assistthe insulation in maintaining the temperature.l ,It is very inconvenienttol have 'to v'remove thefcork every time `rit is :desired to use thebottle in order to .gain access to the'liquid therein.

` My` invention has for its obj ect to provide a'nfalucet which can bemountedfinthe cork and. which will enablet'he user to secure the liquidcontained in the container without the necessity of removing the corkat' all. The ordinary aucetis 'of novalue for this purpose inasmuch asno provision is made for the entrance of'air to take the space occupiedby the discharged liquid. In my improvement ample provision is made forthe entrance ot the air so as to insure a full and continuous flow ofliquid.

My means of accomplishing these objects may be more readily understoodby having reference to the accompanying drawings which are heretoannexed and are a part ofthis speciiication in Ywhich as shown in thedrawings: y f y Fig. 1 is a fragmentary view of a thermos a bottleequipped withjmy improvement;

`Fig. 2 is a detail view; Figs. 3, 4 and 5 are detail views of parts ofthe device.

Similar reference numerals referto similar parts throughout the entiredescription. As shown in the drawing the bottle, 1, is

)rovided with a cork, 2, in the usual manner.V

his cork is. provided with longitudinally extending opening or passage,3, in which is mounted a cylinder 4, whichA is provided with a pluralityof external threads, 5, cut upon its end, 6. A circumferential flange,7, is formed on the cylinder and is adapted to and does abut the outerend, 8, of the cork. "A nut, 9, having an opening, 10,

therethrough, which is provided withv Speci'cationof Letters Patent.Patented API.. 4 1922 f y v Application filed December 16, 1921.V SerialNo. 522,820.

l threads, 11', which are Afitted toiand coinfy cide with the threads',5,cut upon the ends,

6, of the"cylindricaljsleeve, 4, serves to draw the' flange,4 tightlyagainst the; face, S, ofthe cork, 2, thus preventing leakage .oftlievliquid.V Lugs, 12 and 13, are provided on the nut, 9, forconvenient manual manipulation. Thefgouterrend, 24. of the cylinder 4,is provided with fan opening. 14, 1 n its lower vwalland anL air vent oropening, 15, in its top wall. The outer surface of the end, 24 ofthecylinder, is ground yand slightlyxtapered to fit .the taper ofA asleeve,y 16, which Lis rotatably mounted thereon. VThe cylindricalsleeve, 16 is provided ,with two .outwardly extending lugs,

17 and .18, through whicliextend portsor passages; 1 9 and 2O .whichfareadapted rto register withthe openings 14 and`15,'in

the 'end 24, of the cylinder, 4. I The cylin drical sleeve, 16, isheldon the-tapered'. end,

24, sol as to yforma .tight `joint bymeansy 'u' i of 'aknurled 'nutVorpin any other suitable n orconvenient manner, a coil spring231 be-.ingprovided lto keep the joint tight.

sok

When it is desired'to obtain liquidy l:from the inside of the bottle, 1,it is tilted up and Y the cylindrical sleeve, 16 is turned until thelug, V18, is in register with the opening, 14, when as is obvious theliquid will flow out into a cup or other desired receptacle. This flow,however, would be more'or less intermittent due to the liquid beingairbound unless a proper air vent is provided. It

-will bev apparent that. the operation of bringing the port or passage,19 ,formed in the lug 18, in register with the opening, 14, serves atthe same time to bring the port or passage, 20, formedk in the lug, 17,in register with the opening, 15, through which the air may enter intothe interior of the Wardlyrextendi'ng lugs `on said sleeve'havingpassages therein vadapted to register withV parent that any of thenumerous devices ern-- Vployed for this purpose may be utilized Withoutdeparting from my invention,
